CAR-WH EEL.

SPECIFICATION forming part of Letters Patent No. 498,038, dated May 23,1893. Application filed August 10, 1892. Serial No. 442,672- (No model.)

To all whom it may concern.-

Be it known that I, JOSIAH A. WEBBER, a citizen of the United States,and a resident of Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in Oar-Wheels,of which the following is a specification.

My invention relates to car wheels and itis an improvement upon theinvention for which I obtained Letters Patent of the United States,dated October 27, 1891, No. 461,859. In wheels made in accordance withthat former invention, the brakes were applied upon the periphery ortread of the wheel in the same manner that they are applied upon thetread of ordinary wheels.

My present invention consists in supplying a surface upon which thebrake can act which is located at the side of the wheel instead of uponthe periphery or tread thereof.

I also embody certain improvements in the construction of my presentwheel which will hereinafter be described.

Figure l of the drawings, illustrates a vertical section of a car wheelembodying my invention on the line 51;, x, of Fig. 2. Fig. 2 is anelevation taken from the right in Fig. l.

A is the hub of the wheel. It is provided on one side with a flange B.

O, O are two side plates which afford lateral support for the wheel. Theplate at its edge is thickened as at D and is provided with the ordinaryflange E.

F, F, are the disks of non-metallic material which form the majorportion or body of the wheel. They lie between the disks 0 and C.

G, G, &c., are bolts which pass through the flangeB of the hub A andthrough the plates 0, and C, and through the disks of non-metallicmaterial F, if they extend so far toward the hub and by means of thesebolts the structure as thus far described is firmly clamped and rigidlyheld together.

I now come to the feature which in conj unction with that which hasalready been described, characterizes this invention. H is an annularcasting of suitable material; in its back side are formed toothed orsimilarly shaped recesses I, I, (850., into which fit teeth or similarprojections J, J, formed in the thickened part D of the plate 0; and onthe interior edge of the annular casting H are also formed otherrecesses and teeth L, L, which interlock with similarshaped projectingparts MM, on the flange B of the hub. N, N, &c., are a series of boltswhich pass through the annular casting H, the side plates 0 and O, andthe disks of non metallic material F, F, whereby the annular casting His firmly clamped to the wheel and also the outer portions of the wheelitself are rigidly held together. The purpose of the interlockingsurfaces I, J and L, M, between the annular casting H and the thickenedpart D of the plate 0' and also between the annular casting and theflange B of the hub is so that the act of applying the brakes upon theperiphery O of the annular casting H may be prevented from shearing offthe bolts N, N, &c., the strain is sometimes enormous and althoughordinarily the bolts N would be sufficient to hold the parts rigidly toeach other, especially if there are a large number of them as shown,nevertheless the interlocking surfaces afford an absolute preventionagainst the shearing of the bolts. The construction of the wheel is,however, so much simpler when these interlocking surfaces are notemployed, that I do not always use them. A illustrates a brake-shoeshowing one method in which it may be applied upon the friction surface0 of the annulus H.

It will be obvious to those who are familiar with this art thatmodifications may be made in the details of construction shown and stillthe essentials of my invention be employed. I do not therefore limitmyself to such details.

I claim- 1. A car wheel comprising essentiallya metallic hub, a nonmetallic center portion, side plates one of them provided with a flangefor the wheel and an annular casting or friction plate fastened upon oneof said side plates, substantially as set forth.

2. A car wheel comprising essentially a metallic hub, a non metalliccenter portion, side plates one of them provided with afiange for thewheel, an annular casting or friction plate and bolts passing throughsaid annular casting through said side plates and through the nonmetallic center portion and means whereby the body of the wheel may befastened to the hub, substantially as set forth.

3. A car wheel comprising essentially a metallic hub, a non metalliccenter portion, side plates one of them provided with a flange for thewheel, an annular casting or friction plate, means to fasten thefriction plate to the side of the wheel and interlocking parts betweenthe wheel and the annular casting or friction plate, substantially asset forth.

4. A car wheel comprising essentially a metallic hub, a non metalliccenter portion, side plates one of them provided with a flange for thewheel, an annular casting or friction plate, means to fasten thefriction plate to the side of the wheel and interlocking parts betweenthe wheel and the hub and the annular casting or friction plate,substantially as set forth.

5. A car wheel comprising essentially a metallic hub, a flange upon thehub, side plates one of them provided with a flange, non metallic disksextending from the hub to the tread of the Wheel, an annular casting orfriction plate, bolts passing through the flange of the hub, the sideplates and non metallic disks and other bolts which pass through platesand the non metallic disks, and interlocking surfaces between theannular brake ring and the body of the Wheel, substantially as setforth.
